When the turntable 5 rotates, it drives the inner top pieces 4 to slide, and the inner top pieces 4 slide along the slide groove 6 in the direction away from each other; with the help of the guiding effect of the guide groove 3, the inner top pieces 4 slide along the radial direction of the inner circle of the workpiece until the inner top pieces 4 are in extrusion contact with the workpiece.

[0068] With the help of three inner top pieces 4 that are distributed on the circumference and at intervals, the workpiece is clamped and fixed. During the sliding process of the inner top piece 4, the workpiece can be centered to ensure the consistency of the center of the workpiece during processing. At the same time, with the help of the sliding of the inner top piece 4, the versatility of the inner top piece 4 is improved, the applicable range of workpiece models is expanded, the comprehensive processing capacity of the equipment is improved, the idle time of the equipment is reduced, the equipment utilization rate is improved, and the equipment cost is reduced.

[0069] Example 2, refer to Figure 1 to Figure 8, which is the second embodiment of the present invention, combined with the first embodiment, on the basis of the connection hole processing system including the processing table 1, the guide rail 2, the inner top piece 4 and the turntable 5, a power output head 14, a tool fixing unit, a power output seat 25 and a tool seat 16 are further added; wherein the tool fixing unit includes a guide bar 17, a locking pin 19, a stopper 20, a limit ring 21, a spring 22, an auxiliary lock head 23, an unlocking member 26, a latch 27, a linear drive 4 28, a clamping frame 29, a clamping member 30 and a linear drive 5 32; the linear drive 4 28 and the linear drive 5 32 are preferably hydraulic cylinders in the prior art. The number of tool fixing units is two, which are symmetrically distributed on both sides of the tool, and every two tool fixing units form a group of fixed knives, and there are two groups of fixed knives in total, which are symmetrically distributed on both sides of the power output seat 25. Further, a clamp 33, a tool storage table 34 and a transport chain 35 are added. The number of power output heads 14 is preferably two, corresponding to the number of fixed knife groups, and each power output head 14 works independently.

[0070] Before work, the tool and the tool holder 16 are connected together. The tool holder 16 is a universal part, and different models of tools are selected according to processing needs; then the tool holder 16 equipped with the tool is clamped on the clamping table part 37 of the tool storage rack 36 through the clamping part 33; the sprocket is driven by the built-in power source on the processing table 1 to drive the transport chain 35 for circular transportation; the connecting hole processing system is externally equipped with a controller, which controls the conveying state of the transport chain 35 and the operating state of the linear drive four 28 and the linear drive five 32 at the same time.

[0071] The operation process is described starting with taking the cutting tools from the transport chain 35. During operation, the two groups of fixed cutting tools are respectively located on the upper and lower sides of the power output seat 25 (the upper side is defined as fixed cutting tool A, and the lower side is fixed cutting tool B). At this time, fixed cutting tool A is aligned with the cutting tools to be used on the transport chain 35; at this time, the linear drive five 32 is in a retracted state, the clamping member 30 and the latch 27 are in a separated state, and then the linear drive four 28 is started and begins to extend. The power output by the linear drive four 28 will drive the clamping frame 29, the latch 27, the clamping member 30, and the linear drive five 32 to approach the cutting tools synchronously. The latch 27 is opposite to the unlocking hole 24 and gradually approaches the unlocking hole 24 until the end of the latch 27 passes through the unlocking hole 24 and is exposed for a distance, and then the latch 27 stops moving.

[0072] When the end of the latch 27 passes through the unlocking hole 24, the latch 27 is squeezed and contacted with the unlocking piece 26. With the help of the squeezing of the latch 27, the unlocking piece 26 gradually approaches the locking hole 18 and finally stops on one side of the locking hole 18. At this time, the protrusion on the unlocking piece 26 is just located in the locking hole 18; then the working state of the linear drive five 32 is adjusted from contraction to extension. With the help of the power output by the linear drive five 32, the clamping piece 30 starts to rotate, and the opening groove 31 gradually approaches the end of the latch 27 passing through the locking hole 18. Finally, the opening groove 31 is clamped on the latch 27. At this time, the guide bar 17 is located on the latch 27; the two latches 27 in the same group of fixed knives are respectively inserted into the corresponding guide bars 17; at this time, the tool is grasped.

[0073] Then adjust the working state of the linear drive four 28 from extension to contraction, and take the tool out of the card table part 37; the linear drive four 28 stops power output after contracting a certain distance; then the linear drive four 28 starts to rotate with the help of the power output of the external power source, and the linear drive four 28 stops rotating after rotating one hundred and eighty degrees. At this time, the tool on the linear drive four 28 is just facing a power output head 14; then the linear drive four 28 starts to extend until the tool on the linear drive four 28 is located above the power output head 14, and at this time the guide bar 17 is just aligned with the guide groove two 15; a telescopic cylinder is provided on the power output seat 25, and the linear drive four 28 is rotatably arranged at the free end of the telescopic cylinder; with the help of the contraction of the telescopic cylinder, the guide bar 17 gradually approaches and is inserted into the guide groove two 15.

[0074] The spring 22 is in a non-stretched state, the upper limit ring 21 of the power output head 14 is in contact with the stopper 20, and after the guide bar 17 enters the guide groove 15, the auxiliary lock head 23 gradually approaches the lock pin 19 following the sliding of the guide bar 17; at this time, the auxiliary lock head 23 first comes into contact with the lock pin 19 by compression, and with the help of the compression of the auxiliary lock head 23, the lock pin 19 squeezes the spring 22, and the spring 22 contracts and accumulates elastic force; as the guide bar 17 continues to slide, the lock pin 19 is finally aligned with the locking hole 18, and the guide bar 17 stops sliding at this time, and then the linear drive five 32 begins to contract, and the clamping member 30 gradually rotates in the direction away from the latch pin 27 until the opening groove 31 is completely separated from the latch pin 27, and the linear drive five 32 After contracting to a preset state, it stops contracting; then, the linear drive four 28 begins to contract, and the pin 27 starts to slide simultaneously with the contraction of the linear drive four 28, and the pin 27 slides in the direction away from the unlocking member 26, and the distance of the pin 27 makes the unlocking member 26 in a free sliding state; at the same time, the spring 22 releases the accumulated elastic force, pushes the locking pin 19 to insert into the locking hole 18, and pushes out the protrusion in the locking hole 18, with the help of the locking pin 19, the guide strip 17 and the power output head 14 are fixedly connected, and the tool is fixed; when the pin 27 is separated from the unlocking hole 24, the linear drive four 28 runs to the preset position and stops moving; at this time, the tool is fixed on the power output head 14.

[0075] Then, with the help of an external power source, the power output seat 25 is driven to start rotating, and the first fixed knife rotates downward synchronously with the standby tool. After rotating 180 degrees, the rotation of the power output seat 25 stops. At this time, the first fixed knife is located on the lower side of the power output seat 25, and the second fixed knife is located on the upper side of the power output seat 25; then the power output head 14 on the lower side starts to work, and with the help of the three-dimensional moving components in the prior art (not shown in the attached drawings), such as a mechanical arm, the tool is moved to the top of the workpiece to start processing the connecting hole. When the tool needs to be replaced, the fixed knife can be separated from the power output head 14 by operating in the reverse direction, which is convenient to operate, saving time and effort; at the same time, when the lower power output head 14 is working, the upper fixed knife can complete the replacement of the next set of tools, improve the efficiency of tool replacement, shorten the equipment standby time, and improve the processing efficiency.

[0076] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
